Thanks for posting! I agree, I think our Series 770 looks like a good match. I'm not so sure about the stamp though. What is the weight of your window sash? I'm thinking you might need a 22F option, but since that is not standard, such a balance will have to be custom made. I think it's best that we know what your window sash weight is before we go any further down that road.

Ah, I see. I do not recommend trying to switch springs. There is a lot of tension on these springs and they are not meant to be replaced like that.
I was right -- you will need a 22F option. Take a look at this Custom Channel Balance Request Form that I have started for you based on your specifications and fill out the rest of the information. One of our representatives will get back to you with a price quote shortly thereafter, and you can decide what you want to do from there. |
